PART I <br />Page No. 8 <br />Petmit No. COG-850000 <br />B. EFFLUENT LIIKITATIONS AND MONTTORIIYG REQUIItEMENTS <br />2. Stormwater Mana¢ement Plan (SWMP) (continued) <br />3) Stotmwater Quality Controls <br />Each mining site covered by this permi[ shall develop a description of stotmwater quality controls appropria[e <br />for thaz si[e, and implemen[ such controls. The appropriazeness and priorities of convols in the plan shall <br />reflect identified potential sources of pollutants at the site. The description of stormwater quality controls shall <br />address the following minimum componenu, including a schedule for implemen[ing such convols: <br />a. SWMP Administra[or -The SWMP shall identify a specific individual or individuals within the mining <br />organization who is responsible for developing the SWMP and assisting the mine operator in its <br />implementation, main[enance, and revision. <br />b. Materials Handline and Soill Prevention -Where materials can impact stormwater runoff, BMPs that reduce <br />the potential (or contamination shall be described. For example, materials should be stored and handled in <br />covered areas whenever possible to prevent contact with stormwater; fuels and other chemicals should be <br />stored within berms or secondary containment devices to prevent leaks and spills from entering stormwater <br />runoff. <br />c. Erosion and Sediment Controls - Describe BMPs tha[ will be used [o reduce erosion and preven[ sedimen[ <br />delivery to State waters. These should include structural (such as silt fences, sediment ponds, drop <br />strocnves, check dams) and non-structural (such as mulching and revegetation) methods. <br />Whenever a facility or a portion of a facility enters the Host-minine phase, it is likely that the overall <br />configuration of the site will change considerably. Prior to the time when new vegetation becomes <br />established, the surface aeeas will be subject to potentially significant erosion. The permittce will need to <br />take adequate measure in order to m;n;mne this crosion as well as the erosion normally encountered <br />during mining activi[ies. <br />d. identification of Discharees other than Stormwater -The stormwazer conveyance system on the site shall be <br />evaluated for the presence of dischazges other [han stormwater, such as mine drainage, spoil springs, <br />sanitary waste, or process water of any kind. The SWMP shall include a description of the results of any <br />evalttazion for the prescnce of discharges other than stormwarer, the method used, the date of the <br />evaluation, and the on-site drainage points that were directly observed during the evaluation. <br />b) Facility Insoeaions <br />Qualified personnel identified by the operator shall make a comprehensive inspec[ion of their stormwater <br />managemrnt system, at least twice per year (in the spring and fall), ezcep[ as provided in paragraphs d and e, <br />below. These comprehensive inspections must be documented and summarized in the Annual Report (see Pan <br />1.D.2. of [he permit). <br />1) Material handling areas, disturbed areas, areas used for material storage that are exposed to precipitation, and <br />other potential sources of pollution identified in the SWMP in accordance with Part 1.B.2.a)1) of this permi[ <br />shall be inspected for evidence of, or the potential for, pollutanu entering the drainage system. Structural <br />stormwa[er management measures, sediment and convol measures, and other structural pollution prevention <br />measures identified in the plan shall be observed [o ensure that they are operating correc[ly. A visual inspec[ion <br />of equipment needed to implement the plan, such as spill response equipment, shall be made. <br />2) Based on the results of the inspection, the description of potential pollu[ant sources and pollution prevention <br />measures identified in the plan shall be revised as appropriate within two wceks of such inspection. Such <br />revisions shall provide for implementation of any changes to the plan in a timely manner, but in no case more <br />than 90 days after the inspection. <br />
